关于向量丛的泊松代数刻画

On a Poisson-algebraic characterization of vector bundles

Elie Zihindula Mushengezi

AI总结:

该研究证明微分算子符号的$\mathbb{R}$-代数无法仅靠代数结构刻画向量丛,而其泊松代数结构无需${\rm C}^\infty(M)$-模条件即可实现向量丛的刻画。

摘要:

我们证明,作用于向量丛$E\to M$的截面的微分算子的符号构成的$\mathbb{R}$-代数$\mathcal{S}(\mathcal{P}(E,M))$可分解为和式$\mathcal{S}(\mathcal{P}(E,M))=\mathcal{J}(E)\oplus {\rm Pol}(T^*M)$,其中$\mathcal{J}(E)$是$\mathcal{S}(\mathcal{P}(E,M))$的一个理想,且该理想中任意两个元素的乘积恒为零。这表明$\mathcal{S}(\mathcal{P}(E,M))$无法仅凭借其$\mathbb{R}$-代数结构刻画$E \to M$。我们证明,借助其泊松代数结构,$\mathcal{S}(\mathcal{P}(E,M))$无需被视作${\rm C}^\infty(M)$-模即可刻画向量丛$E\to M$。

英文摘要:

We prove that the $\mathbb{R}-$algebra $\mathcal{S}(\mathcal{P}(E,M)) $ of symbols of differential operators acting on the sections of the vector bundle $E\to M$ decompose into the sum \[ \mathcal{S}(\mathcal{P}(E,M))=\mathcal{J}(E)\oplus {\rm Pol}(T^*M) \] where $\mathcal{J}(E)$ is an ideal of $\mathcal{S}(\mathcal{P}(E,M))$ in which product of two elements is always zero. This induces that $\mathcal{S}(\mathcal{P}(E,M))$ cannot characterize $E \to M$ with its only structure of $\mathbb{R}-$ algebra. We prove that with its Poisson algebra structure, $\mathcal{S}(\mathcal{P}(E,M))$ characterizes the vector bundle $E\to M$ without the requirement to be considered as a ${\rm C}^\infty(M)-$module.
